Dangerous part of Off-Roading

4x4addict · 8th July 2010, 20:15

Most of us enjoy off-roading and it sure is fun. I was youtubing off-road accidents and there are the usual ones caused by sheer stupidity or Darwinism (depending on how you look at it).

But this video of a Montero rolling over absolutely shocked me. It seems to be just backing up slowly but guess the tires got wedged in a rut and the weight pulled the vehicle over.

Really, Really Scary !!

Do you think steering the wheels into the opposite direction of what he did would have helped. You normally steer into a slide going forward but I guess you can't do that when you are doing it in reverse.

Am I correct?

The front wheels were not touching the ground at all, so steering was useless anyway.

@ 4x4addict: You've pointed to a mine of fantastic videos of exactly what NOT to do when off-roading!

Especially these three...

YouTube - Mitsubishi Pajero off road crash

YouTube - DEFENDER 90 ROLL OVER

YouTube - D90 Rollover in Montrose

Your (and all the other OTR experts') analysis of what went wrong to get these results, would be looked forward to eagerly!

Check between 0:08 and 0:10, the front wheels are on the ground. Was referring to steering error at that time.

It appears that in the first post the vehicle is trying to climb a very steep slope. Of course, due to video angle, its not easy to figure this out.
As it starts going backwards, the driver errs in making the vehicle sideways, and this leads to the rollover.

It is very hard to judge the terrain, especially the angle unless you are standing there.

First video is from Australia, need proper angle to find out..

Mitsubishi Pajero off road crash

: Never take an incline at an angle. Always straighten up and do it. If Prithvi is here, he knows I made that cardinal sin once and got away with my life :-)

YouTube - DEFENDER 90 ROLL OVER

: Mistake one: he probably did it in a higher gear on the main GB though on low ratio. He probably thought the vehicle will slide rather than roll if he was in a lower gear (much like Sharath's incident - apologies man, just taking a reference).

Mistake 2: He braked and turned out of the rut instead of continuing to remain in it. Reflex action considering the way he bobbed and jumped up and down.

YouTube - D90 Rollover in Montrose

: Cannot see the terrain he was heading up into. Will be wrong to issue a fatwa ;-)

I almost had a sixth sense that you will bring it up again here.

But there are major differences. He was lot faster, that a slight sidewards slide resulted in rollover. His steering was always straight, and he didn't try to counter the right turn by turning the steering to the left. The jeep I was driving turned 90 degree since the steering spun out of control to the right. Still the Jeep didn't rollover right away since the speed was not much. I didn't brake at any point and instead countered the turn by turning fully left and regained the track.

Still I have a feeling you are going to keep bringing this up forever...

The first video of Pajero toppling in SS_traveller comment was due to higher acceleration and the defender 90 rollover was due to turning the steering very early and fast causing the machine to topple.

xtreme power · 9th July 2010, 12:42

for some reason, in the pajero toppling video
i think it was the speed that made it topple,
had he gone slower, he'd realise the extent of his stupid approach

Hey nice thread. While there are too many good threads on how exciting, adventerous, etc etc offroading can be - there is none to SHOW how dangerous it can get. Keep them rolling guys - u-toobe has too many such good informative vids of bad things that happen in a OTR trail.
